A Sense Of Touch For Robotic Surgery Tools

A Sense Of Touch For Robotic Surgery Tools
By substituting mechanical instruments for human fingers, robotic tools give surgeons a new way to perform medical procedures with great precision in small spaces. But as the surgeon directs these tools from a computer console, an important component is lost: the sense of touch.

Johns Hopkins scientists are trying to change that by adding such sensations, known as haptic feedback, to medical robotic systems. "Haptic" refers to the sense of........Go to the Research news blog (Added on 11/29/2006 5:09:01 AM)

The impact of immunosuppressive medications

The impact of immunosuppressive medications
Patients with rheumatoid arthritis (RA) have an increased risk of heart attack and stroke. As per extensive evidence, the key driver for this increased risk of cardiovascular disease is the increased systemic inflammation characteristic of RA. Studies are less clear on whether medications that work to reduce RA's inflammatory symptoms provide protective benefits against cardiovascular events. Some data have suggested that the most potential........Go to the Rheumatology news blog (Added on 11/29/2006 4:34:08 AM)

Don't Understand Prescription Medicine Labels?

Don't Understand Prescription Medicine Labels
When Michael Wolf paged though dusty, yellowing pharmacists logs from the 1890s at the Smithsonian National Museum of American History, he found the following entry about a druggists encounter with a confused patient: Shake well, a patient apparently read out loud to the pharmacist from his prescription bottle label. Does that mean I shake myself".

It sounds like a campy '50s horror movie ("It Came from the Ice!"), but a Bowling Green State University biologist believes it's a very real possibility. Dr. Scott Rogers is talking about the potential for long-dormant strains of influenza, packed in ice in remote global outposts, to be unleashed by melting and migratory birds.
